. VALVE FOR sTEAM-TRAPS.

SPECIFICATION forming part of LettersPatent No, 284,469, dated September 4, 1883.

` Application madonna 9,1883. (No model.)

. To aZZ whom. t may concern:

Be it known that I, ROBERT NEWTON, `of the city and county of Providence, and State of Rhode Island, have invented a new and use 5 ful Improvement in Valves for Steam-Traps; and I hereby declare the following to be afull, clear, and .exact description of the same, refer-- ence being had to the accompanying drawings, forming part of this specification. A

This invention has reference to an improvement in the valves of steam-traps, by which the water of condensation from the steam is automatically carried off without the lossof steam. I 5. The invention consists in the 'novel and peculiar construction of the valve and the connectionwith the steamfoutlet, as will be more fully setforth hereinafter.

Figure lis a view of my improved valve. 2o Fig. 2 is a sectional view of the same. Fig. 3 is a sectional view of a steam trap, showing the application of my valve to a steam-trap.

In the various forms of valves for steamtraps thevalve is always more or less liable 25 to stick, and thus either close the outlet or leave the same open, allowing the steam to escape. This is caused in the valves constructed on the .principle of the faucet by the fric,- tion of the `annular case on the tapering hollow 3o stem and the liability of impurities entering between the surfaces, causing a wedging and binding of the parts. In the class of valves inwhich the valve slides inside of a case the whole pressure due to the steam in the pipes 35 and the weight of the condensed water presses thevalve against the case, so that it is moved i with difficulty. To overcome `these defects IY construct my improved valve on the oscillating principle, .and hold the same to its seat by 4o ayielding connection, by which all wear is the outlet, the water `5c `3 on a level with the outlet D, through which make a tight joint.

` perfect fit. l t

Having thus described my invention, I claim 9o y all water escapes, and by which the water-level is preserved uniform. n

E is a tubular stem, forming the inlet C. .It is provided at one en d with the screw-thread e, so that the pipe to be drained can be con- 5 5 nected with the same and with the shoulder e, between which and the side c of chamber Aany suitable packing may be interposed to rEhe opposite end of thej stem Eis provided with the valvechamber e3, having the port e4 and the air-vent e5. It has a concaveseat, in which the elbow F can i oscillate to open and'close the port cAL and the airvent e5, as is clearly shown in Figs. 2 and 3. The elbow F is provided with trunnions ff, and these are supported in the bearings f `f, secured to the rods f 2 f2, the ends of which pass through the yoke f3, which is forced upward, so as to hold the valve-face of the elbow F in contact with the bearing of the valve chamber e3 by the coiled spring f4, placed around a central guide-rod. It is obvious that coiled springs may be placed around the rods f2, instead of between the same.

^ -Gis a pipe connecting the elbow F with the sphere H, the end `beingclosed by the hinged gate-valve g. The sphere His provided with the small hole h, by which the sphere is gradually filled. i

I is the discharge-pipe or vomit.

By the peculiar construction of this valve great leverage is secured to move the same .by the rising or falling of the sphere, while by'the adjustable spring-tension the surfaces are .held in' contact, so as'to wear evenly 'and 85" maintain a tight fit. .The construction of the valve `is simple and economical, and` all the wearing Of the parts in contact insuresa more supported in trunnionsaand held against the Ioo -va1veseat by means of a spring or springs l Valve to regulate the flow of Water automatieonstrueted to hold the surfaces in Contact, as cally, as described.` descrbed ROBERT NEWTON- 3.
